ALBERT A. GEHRT,OF QUINCY, ILLINOIS, ASSIGNOR TO THE COLLINS PLOIV COMPANY, OF

BALING- SPECIFICATION forming part of Letters Application filed February 1, 1889.

To e55 whom it may concern:

Be it known that I, ALBERT A. Guitar, of Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Improvement in Baling-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which-- Figure I is a detail top view of a balingpress with the baling-chamber in section, illustrating my improvement. Fig. II is a similar view showing the parts in a different position. Fig. III is a detail side elevation.

My invention relates to the manner of forming the sweep-head in conjunction with the manner of connecting the pitman to the head; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the usual frame-work of a baling-press; 2, the

man, and 5 the sweep, loosely pivoted to the frame-work by means of a vertical rod 7.

6 represents the sweep-head, also loosely pivoted to the rod 7, from which it projects in opposite directions. It is preferably so pivoted that it projects farther in the direction of the pit-man than in the direction of the sweep, or, in other words, it is preferably eccentrically pivoted to the frame of the press, with its longer end toward the pit-man. The short cessed portion 10f In this recessed portion works a pin 11, fitted in the sweep 5, the sweep preferably being bifurcated or forked at its inner end, as shown in Fig. III, so as to straddle the sweep-head. hen the sweep is moved in the direction indicated by the ar-' projections 9, and when the sweep is moved in the other direction it bears against the other projection 9.

The end 12 of the sweep-head is provided with a slot 13, preferably in the form of a horseshoe, or a shape approximating that of ahorseshoe. In the slot 13 fits a frictionroller it on the outer end of the pitman 4,

and the pitman is thus connected to the sweep-head.

Theoperation is as follows: The parts being in the position shown in Fig. I, the sweep is moved in the direction indicated by the arrow from the position shown in Fig. I to the position shown in Fig. II. As it is thus moved, the outer face 15 of the slot 13 bears against the roller 14, and gradually forces the traverser to its forward position. As the traverser advances, the roller 14 approaches the pivotal center of the sweep-head, and thus speed is converted into power, the movement of the traverser being rapid during the first part of the movement of the sweep, when little power is required, and being slow during the latter part of the movement of the sweep, when a great amount of power is re quired. As soon as the point of bearing be tween the outer end of the pitman and the sweep-head passes the center line of the trav- 7o erser or passes the position shown in Fig. II, the sweep-head will turn on its pivot from the position shown in full lines, Fig. II, to the position shown in dotted lines, thus allowing the traverser to rebound. Then the sweep is 7 5 moved in the other direction, (the pin 11 bearing against the opposite lug 9 to that which it bore against when the sweep was moved in the direction just described,) and the traverser will then be forced forward again.

By constructing the machine in this manner there are very few parts, which at once affords cheapness in construction and little liability of getting out of order, and a ma- 8 5 chine thus constructed is also light and eas ily operated.

I claim as my inveniion- 1. The combination, with a traverser and a pitman, of a sweep-head formed with a slot 96 13 of horseshoe shape on one side of the pivot, and with lugs 9, forming a recess 10 on the other side of the pivot, and a sweep having a pin playing in the recess and bearingagainst the lugs, substantially as described.

2. The combination, with a traverser and a pitman, of the sweep-head formed with a slot 13, and with lugs 9, forming a recess 10,

and eccentrically, pivoted to the framework l and a sweep 5, loosely pivoted to the rod,

of the press, and the sweep having a pin and having a pin 11 playingin the recess and to playing in the recess and bearing against the bearing against the lugs-substantially as delugs, substantially as described. scribed.

5 3. The combination, With a traverser and a pitman, of a vertical rod 7, a sweep-head formed with a slot 13, and with lugs 9, forming a recess 10, and loosely pivoted to the rod,-
